THREAD-CASE FOR SEWING-MACHINES.

3ZECIF1GATIN forming part of Letters Patent No. 324,240, dated August 11, 1885.

Application filed June 23, 1885. (No model.) Patented in Enganll April 2.), 1885, No. 5,328.

To all whom, it may concern: Be it known that I, ALGERNON DEWHURST, a subject of the Queen of Great Britain and Ireland, and a member of the firm of John Dewhurst and Sons, residing at Skipton, in the county of York, cotton-spinners and sewingcotton manufacturers, have invented certain Improvements -in Thread-Cases for Sewing- Machines or for other Purposes, (for which I have applied for patents in Great Britain on the 29th April, 1885, No. 5,328; France on the 28th May, 1885, and Belgium on the 29th May, 1885,) of which the following is a specification.

My invention has for its principal object to provide cases containing coils of cotton or other thread for use in the shuttles of sewingmachinessuch, for example, as that known as the Singer oscillating shuttle machine, but the said cases containing coils may be used for any other purpose for which they may be applicable, and the essential feature of my invention is the provision of a free passage within the case for the thread from the center of the coil to the periphery of the case, from which part it is drawn off in use.

Figures 1 and 2 of the accompanying drawings represent, respectively, an elevation and a transverse section of a paper and card-board case and inclosed coil of thread, the case being provided with a free passage for the thread, as aforesaid.

The coil of thread to be inclosed in the case is shown in Fig. 3. The case by which it is inclosed is made up of two card-board side disks, which are placed one on either side of the coil of thread.

The disk, Fig. 4:, is a plain disk, but the other, Fig. 5, has a gap, a, extending from the center and out at the side. Over this lat ter disk the ticket, Fig. 6, is pasted. Fig. 7 shows a plan and section of this disk and ticket gummed together. The gap a is placed over the end of the thread I), which lies along the side of the coil from the center to the periphery, the gap at giving a free passage for the thread between the side of the thread-coil and the ticket, as shown in Fig. 2, which is enlarged for the purpose of showing this more clearly. The two disks arev joined by a strip,

of paper, Fig. 10, having a slit in it at c for the passage of the thread. The card-board strip is not long enough for its ends to meet round the periphery of the coil, so that there is a gap, (1, left between the ends for the thread, the said gap forming a continuation of the gap a in the side disk.

- Fig. 11 shows the combined strip placed ready for the sides of the paper portion to be gummed to the two disks, Fig. 1 showing the coil and case completed by this operation.

Figs. 12 and 13 represent views at right angles to each other of a metal case made up of two disks, one placed as in Fig. 14, and the other (shown in Fig. 15) having a passage, a", for the thread on its inner side. The said disks are placed one on each side of the coil, and arejoined by a strip, Fig. 16, with ears, which are bent down over the disks to secure the parts together, in a manner like that by which the parts are secured by the paper strip in the preceding example. The passages inside the case for the free passage of the thread are made by stamping up the groove or depression 0 0 in the one disk in line with a groove or depression, (1 in the side strip, which has also a slot, 0 for the passage of the thread to outside the case.

I claim- 4 1. A thread-case for sewing-machines, provided on the inside with a free passage or channel for the thread, said channel being formed in one of the sides of said case, and extending from the center to the periphery thereof, substantially as described.

2. A case for containing a coil of thread, the same comprising end disks, one of which has a thread passage or channel extending from its center to its edge, and a strip connecting said disks and forming the periphery of the case, substantially as described.

3. A cylindrical thread-ease having in one of its circular ends a channel or passage for the thread running from the center to the edge thereof, the periphery of said case being also provided with a channel or passage forming a continuation of that in the end of the case, substantially as described.

4. A thread-case comprising two disks of In testimony whereof I. have signed my cardboard or similar material, one having a name to this specification in the presence of gap extending from its center to its edge, a two subscribing witnesses. disk of paper placed over said disk, and a 5 connecting-strip formed of a card-board strip ALGERNON DEWHURWF.
